better spend more money and invest bigger engine..

This is sound advice. Other than the little things like a change to 3.0 cams, chipping, etc. If your tuning gets any more serious than this, your starting point should be the engine that's closest to your requirements off the shelf because every step from then on costs money and takes you into the unknown in some respects. This means the biggest one Wink

unless you need to keep below a certain capacity for some reason or the smaller engine is stronger.

I still think the exhaust is worth playing with, though. A properly designed exhaust will wake the engine up in the midrange.

Sep 2007 at 19:59 Seems a pity to dump the Y26 when a Y32 is not that cheap - I don't want to spend a fortune - just see what is easy. Cams - no-one seems to know what is in a 2.6. I reckon that 200bhp is reachable and affordable. Long term would be a Y32SE and AR35 transplant but that would be two years away minimum. (when HP finishes)

Pretty sure it is.

As to "why not swap the car?" well I like it and there are not that many cheap facelifts in good condition

Newer car three isn't many and they also have some sily features like no intermittant wipers, two years time for the Y32/AR35

Personally if I've spent money to buy the car originally, spent lots of time and money getting up to a maintenance level that i'm happy with (serviced regularly, genuine parts, everything working as it should) and therefore feel confident about it's reliability then the last thing I want to do is trade it in so somebody else benefits and then have to start all over again......

For me it's only when a car becomes uneconomic to repair to MOT standard when it's getting older that I would think to change it.
ie. if it was going rotten and two or more other things also needed to be done to get it through.

Just my thoughts!!!

Sep 2007 at 20:49 The last time I start modding I end up with an unhealthy powerful car which I spent twice money than its worth PS: now I dont touch mega other than standard replacements..But even changing sensors make the car more responsive..And I dont plan to sell for a long time also..

That probably didn't end up sounding the way I intended. What I meant is that it doesn't cost any more to start with a 3.2 than a 2.6 and your first 40BHP come for free. Of course if you've already got a 2.6 in your car it's a different matter.

Anyway, my 3.2 is no longer immaculate thanks to a biker who decided to use my front bumper as a safety barrier on a mountain pass in Italy Angry
